g(x) = x^2 from [0,infinity] for less ambiguity, my bad. Question still stands.

Define "single function"... You could create a fourier series for it, but only for finite intervals.

>>8016856
Actually, x*|x|

A piecewise function is still a single function, dipshit

>>8016856
Yes, and you just constructed it using conditional intervals.

I know what you mean, but still. It's a single function by definition.

>>8016875
Thanks man now I feel retarded.
Now let thread be kill.

>>8016885
Hey tripfag, two people have already said that and another presented the function without using interval partitioning. Fuck off. You're not intelligent for replying with this.
I swear just seeing your retarded fucking trip code sends me into a blind rage. Don't tell people your tripcode in real life just in case you happen to tell it to me.

>You're not intelligent for replying with this.
I didn't reply for the intelligence of it, but for the coordinates. If I react to temporal information it tends to destroy that information. Not posting because others did would result in a disparity between timelines if one of the posts that made me decide not to reply was made because a time traveler put it there. This problem literally only occurs because I'm from the future.

>not just filtering him
he's either schizophrenic or a retarded 13 year old who thinks stringing random makes him look smart

why make yourself angry when you can avoid it?

>>8016856
Why do you want to have a function that behaves like that?

>>8017002
>look smart
If you think anything I've ever posted was about looking smart, you either don't know me very well or haven't read more than three of my posts.

>>8017027
then you have some form of mental illness

why else would you insist on shitting up the board with nonsense posts if not for attention

>>8016856
What do you mean by "single function"?

>>8016987
Go back to /x/, role playing scum.

Yes, you just described it

sgn(x)x^2

>>8016880

>>8017006
For the hell of it, thought of it today and couldn't think of one.

>>8016875
the absolute value function is still a piecewise function

>>8017364
x*sqrt(x^2)

f (x)={x^2 for x>=0, -(x^2) for x <0}
:')

superior latex version

[math]
f(x) =
\begin{cases}
\hfill -x^2 \hfill & x \in [-\infty,\ 0] \\
\hfill x^2 \hfill & x \in [0,\ \infty] \\
\end{cases}
[/math]

no point in being good at math if you can't make your math look pretty

>>8017536
I'm on mobile and that looks like shit. Checkmate.

>>8017665
Must you mobile

>>8017671
Nice old phone.
What is it, an S3 ?

>>8017536
no point learning how to make math look pretty if you can't into intervals

>>8018032
for better or worse it's a faithful recreation of OP's specification

>>8016880
How would you phrase it then? At least it's known what it asks for.

>>8017214

please stop with this pedophile shit anon, I've seen this in another thread somewhere not even a minute ago
